Dunham, who’s dating Jack Antonoff, said she had attended the party with Judd Apatow, and Keaton had first asked if they were on a date. But Apatow replied, “No, this is my friend Lena, and she’s significantly younger than me.”

Dunham said of Keaton, “And then she looked at me, and she said, ‘Do you even like men? Are you interested in men?’ It was the best thing. So Diane Keaton was just straight up like, ‘There is a lesbian and I am Diane Keaton so I don’t even need to beat around the proverbial bush. I can just let her know.’”

Dunham spoke at a Lincoln Center Film Society panel with Apatow, where she was wearing an engagement ring. But she said it belonged to Apatow’s wife, Leslie Mann.
